成唯識論述記 9.183

9.183

述曰：此下別也。謂心、心所即自證分及所變現，即相、見分，眾緣生故，如幻事等，非有似有，誑惑愚夫。愚夫等不了，謂為實有，故名誑惑，名依他性。

The Commentary states: From here down is the specific [explanation]. That is, citta and caitasikas are the svasaṃvittibhāga, and what they transform into are the nimittabhāga and darśanabhāga; because they arise from manifold conditions, like illusions and so forth, they are non-existent appearing as existent, deceiving foolish beings. Because foolish beings and others do not understand, and regard them as truly existent, they are called deceptive, and are called the other-dependent nature.
